A stone is fastened to one end of a string and is whirled in a verticla circle of radius R. Find the minimum speed the stone can have at the highest point of the circle.

A stone is tied to a weightless string and revolved in a vertical circle of radius 5 m . What should be the minimum speed of the stone at the highest point of the circle so that the string does not slack ? What should be the speed of the stone at the lowest point of vertical circle ? Take g = 9.8 ms^(2) .

A stone is tied at one end of a 5 m long string and whirled in a vertical circle.The minimum speed required to just cross the topmost position is

A stone is tied to one end of a string and rotated in a vertical circle . What is the difference in tensions of the string at lowest and highest points of the vertical circle ?

IF a stone is tied to one end of the string and whirled in verticle circle, then the tension in the string at the lowest point is equal to

IF a stone is tied to one end of the string and whirled in verticle circle, then the tension in the string at the lowest point is equal to

A stone is tied to the end of a string of length 1 and whirled in a horizental circle. When the string breaks then stone

A stone of mass 5 kg, tied to one end of a rope of length 0.8m , is whirled in vertical circle. Find the minimum velocity at the highest point and at the midway point [g=9.8m//s^(2) ]

STATEMENT-1: One end of a string of length r is tied to a stone of mass m and the other end to a small pivot on a frictionless vertical board. The stone is whirled in a vertical circle with the pivot as the centre. The minimum speed the stone must have, when it is at the topmost point on the circle, so that the string does not slack is sqrt( gR) . because STATEMENT-2: At the topmost point on the circle, the centripetal force is provided partly by tension in the string and partly by the weight of the stone.
